Coronary calcium as a predictor of coronary events in four racial or ethnic groups.
New England Journal of Medicine, 2008 BACKGROUND In white populations, computed tomographic measurements of coronary-artery calcium predict coronary heart disease independently of traditional coronary risk factors.

Calcium, sodium, and the calcium paradox. [PDF]
Circulation Research, 1984 The effect of "sodium loading," of verapamil and of nifedipine on the gain in calcium and sodium, and on the loss of myoglobin, during the calcium paradox in adult rat hearts was examined. Raising cell sodium from 56.5 +/- 2.6 to 129.5 +/- 10.2 mumol sodium/gram dry weight did not alter the degree or rate of calcium gain or myoglobin release during ...

Vitamin D3 and calcium to prevent hip fractures in elderly women.
New England Journal of Medicine, 1992 BACKGROUND Hypovitaminosis D and a low calcium intake contribute to increased parathyroid function in elderly persons. Calcium and vitamin D supplements reduce this secondary hyperparathyroidism, but whether such supplements reduce the risk of hip ...

Preparation, physical-chemical characterisation and cytocompatibility of calcium carbonate cements [PDF]
, 2006 The feasibility of calcium carbonate cements involving the recrystallisation of metastable calcium carbonate varieties has been demonstrated. Calcium carbonate cement compositions presented in this paper can be prepared straightforwardly by simply mixing

Lack of direct evidence for a functional role of voltage-operated calcium channels in juxtaglomerular cells [PDF]
, 1990 In this study we have examined the role of voltage-gated calcium channels in the regulation of calcium in juxtaglomerular cells. Using a combination of patch-clamp and single-cell calcium measurement we obtained evidence neither for voltage-operated ...

Calcium—Nutrient and Messenger
Frontiers in Plant Science, 2019 Calcium is an essential element needed for growth and development of plants under both non-stressed and stress conditions. It thereby fulfills a dual function, being not only an important factor for cell wall and membrane stability, but also serving as a

Calcium Signalling: Calcium Goes Global [PDF]
Current Biology, 2002 Recent evidence suggests that multiple calcium-releasing messengers might be activated simultaneously to regulate patterns of intracellular calcium signalling. In this way, agonists might use different messenger cocktails to encode specific signals and target selected processes.
